I have a dumb amp question

[biffgeiser1]

I probably should have posted this in the new guy forum. But I'd rather get made fun of here.

So, does an amp supply sole power to a component or does it add to power that a receiver already provides?

In other words, if you have a 100wx4 receiver, but you buy a 2 channel amp good for 100w per channel... Does each speaker then get 200w of juice?

I'm kind of dumb with this knowledge so please go easy.

If you add an external amplifier, it basically takes the place of the amplifier section of your receiver. So if your amp is 100wpc and the receiver is 100wpc they don't add. That said, they receiver or amplifier only supplies what the volume level and content call for.

Ahhhh. Now I get it. Thank you!

So if you added the amp would the receiver be a pre-amp? Ive always wondered what a pre-amp is.

If your AVR has a pre-amp out, then yes you would be operating it as a pre-amp (bypass internal amps).

A pre-amp takes a small signal (phono, cd, etc) and amplifies it up to line level and passes the line level over to the amp. Pre-amps usually also have source selection built in too.

Since AVRs also have ability to process the signal (bass management, room EQ, "loudness" curve, etc.) they may also be referred to as 'pre-amp processor', aka. 'pre-pro'.

I think of pre-amps as pure amps, like dedicated phono pre-amps.
